    FANUC Z AXIS SERVO AMP

    HI,
    I HAVE A HORIZONTAL MILL AND BORE MACHINE, FANUC 16M CONTROLLER. THAT HAS A '414 SERVO ALARM Z AXIS DETECT ERROR.' INSIDE THE CABINET THE SERVO AMP FOR Z AXIS HAS AN ALARM CODE OF '1' ON IT. ACCORDING TO ALARM MANUAL I BELIEVE ITS A LOW OR HIGH VOLTAGE ISSUE. ANYONE KNOW HOW I CAN TROUBLE SHOOT OF FIX THIS PROBLEM.
    THANKS SCOT

    could you measure voltage on incoming terminals?
    if it is OK the problem may be in comparator inside the drive
    let us know the model of the drive

    Check your cable from driver to servo motor thats the problem.

    I forgot to add
    if alarm occurs during the operation, the problem may be with discharging transistor or resistor
